On a certain day the barometric pressure at sea level is 30.1 in. Hg, and the temperature is 708 °F. The pressure gage in an air- plane in flight indicates a pressure of 10.6 psia, and the temperature gage shows the air temperature to be 468°F. Estimate as accurately as possible the altitude of the airplane above sea level.

What difference(s) did you notice using a pneumatic circuit over hydraulic circuit. explain why the pneumatic piston stumbles when it hits an obstacle.

Refrigerant 134a enters an insulated compressor operating at steady state as saturated vapor at -26°c with a volumetric flow rate of 0.18 m3/s. refrigerant exits at 9 bar, 70°c. changes in kinetic and potential energy from inlet to exit can be ignored. determine the volumetric flow rate at the exit, in m3/s, and the compressor power, in kw.
